EulerOS 2.0 SP9 : telnet (EulerOS-SA-2024-1948)

high Nessus Plugin ID 202518

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the telnet package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8. In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a 'telnet/tcp server failing (looping), service terminated' error. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8.(CVE-2022-39028)

Tenable has extracted the preceding description block directly from the EulerOS telnet security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected telnet packages.
